Bishops Opening Other Variations Discovered Attack in Chess

A “bishops opening other variations discovered attack” is a discovered attack where a bishop move (or bishop line opening) reveals an attack on a more valuable piece behind it. In many openings within the “other variations” family, a defining feature is a bishop that shifts off a diagonal, unmasking a rook/queen/other bishop’s line toward the king or a pinned piece. The attack is “discovered” because the real threat appears only after the bishop changes the geometry of the position.
